1 Claim.

- This invention relates to a toilet flush valveand hasrelationparticularly to a valve of this kind of a freecball type and it isprimarily an. object of the invention to provide a valve of this kindwhich can be readily applied so that it may be especially used as areplacement for the type of flush valve now generally in use.

It is also an object of the invention to provide a valve of this kindwhere the ball or float is guided in its movements by a sleeve suitablysupported inposition above the outlet opening of the tank.

An additional object of the invention is to provide a valve of this kindwith means to assure the ball or float dropping directly on the valveseat.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved toiletflush valve whereby certain advantages are attained, as will behereinafter more fully set forth.

In order that my invention may be better understood, I will now proceedto describe the same with reference to the accompanying drawings,wherein:

Figure 1 is a view partly in side elevation and partly in sectionillustrating a flush valve constructed in accordance with an embodimentof the invention and in applied position with the ball or float inclosed position on its seat;

Figure 2 is a view similar to Figure 1, with the ball or float in openor raised position;

Figure 3 is a fragmentary view partly in top plan and partly in sectionof the valve as illustrated in Figure 1, the line of section beingsubstantially on the line 3-3 of Figure 1; and

Figure 4 is a view in perspective of the valve unapplied.

In the embodiment of the invention illustrated in the accompanyingdrawings, T denotes a conventional flush tank having a discharge outletI with which is associated an inwardly facing valve seat 2 for the ballvalve member 3. Suitably anchored as at 4, topthe top portion of thevalve member 3 is an extremity of a flexible member 5, the oppositeextremity of which being secured, as at 6, to the free end portion of aconventional rocking trip lever 1. The inlet of water to the tank T ismore or less conventional and as the same'for ms no part of the presentinvention, a detail description thereof is believed unnecessary.

' Under normal conditions with the valve member 3 on its seat 2, theflexiblemember issubstantially taut as shown in Figure 1 but when thefree extremity of the lever I is swung upwardly, the valve member3 willbe raised from its seat 2 to allow the water within the tank T todischarge out through the opening I and throughout substantially thisperiod of discharge, the buoyant pressure of the water within the tankwill maintain the, valve member 3 in its lifted position. It is to benoted that the valve member 3 and the flexible member 5 may be readilysubstituted for the type of valve member, stem and guide bracket nowgenerally in use.

Associated with the valve member 3 is a receiver element R hereindisclosed as a tubular member or sleeve of desired dimensions open atboth ends and which serves as a guide for the valve member 3. The topextremity of the receiver R is provided with a flange 8 extendinginwardly of the side wall 9 of the receiver R to provide a stop toprevent the valve member 3 when lifted from its seat from passing outthrough the top of the receiver.

The receiver R is maintained in desired working position by a bracket Bcomprising an arm I0 provided at one extremity with a split clampingcollar I la to surround the usual overflow pipe I I and be clampedthereto. The opposite or outer extremity of the arm I0 is forked toprovide the fingers l2 spaced apart and aligned in a plane substantiallyparallel to the axis of the collar I la.

soldered, as at I4, or otherwise secured to the outer face of theretainer R, are the adjacent extremities of the arms l5 spaced apart ina general direction circumferentially of the retainer R and having theirfree extremities disposed toward the end of the receptacle R remote fromthe flange 8 and which end is to be known as the bottom. The arms I5 aresubstantially in parallelism and the major portions thereof areoutwardly offset with respect to the retainer R so that one of the saidarm I5 may be readily in serted through the outer end portions of thefingers I2 of the bracket arm Ill. When the arms I5 are applied to thebracket arm Ill, the second arm I5 is carried to overlie the face of thebracket arm Ill remote from the receiver R and in contact therewith sothat the receiver R is maintained snugly and firmly against such bracketarm.

In practice, in the initial placing of the valve, the collar I la isloosely engaged with the overflow pipe I I to allow the arm I0 to bereadily swung to bring the receiver R directly over the discharge outletI and also to permit the arm It! to be ad-' justed lengthwise of theoverflow pipe II to bring the bottom of the receiver R indesiredproximity to the outlet opening I.

As is clearly shown in the accompanying drawings, at all times at leasta part of the valve member 3 is within the receiver and the internal di-OFFICE Y ameter of the receiver R closely approaches the diameter of thevalve 3 with sufiicient clearance, however, to allow the valve member 3to rise or pull freely within the receiver B.

When the lever I is tripped to lift the valve member 3, said valvemember 3 will rise to the top of the receiver R (Figure 2) and be heldthere until the water level within the tank T will permit the member 3to return to its close position with respect to the discharge opening I.

The receiver R serves to maintain the valve member 3 directly inalignment with its closing position.

From the foregoing description it is thought to connecting the valvemember to the trip lever, a

tubular casing to receive said valve member when 4 it is lifted from thedischarge opening by movement of the trip lever, a stop constituted inan inturned edge portion at the top of said casing to retain the valvemember within the casing during its lifting movement, a bracket arm,means for mounting said bracket arm on the overflow pipe, spaced,downwardly angled, arms carried by the casing and outwardly offsettherefrom, one of said second arms, being insertable through an aperturein the'outer portion of the bracket arm, and the second or said armsoverlying and contacting the face of the bracket arm remote from thereceiver to hold the casing firmly against the bracket arm.
